EMBOSSED WALL AND CEILING COVERING.

Application filed October 16, 1913.

cotton cloth. This manufacture has the drawback that the whole web or cloth must be covered directly before the stamping with a layer of a dressing material, in order that it may retain permanently the reliefs embossed on it. The dressing, however, de-

prives the visible surface of the plastic wall covering of its character as a textile ma terial. Now by my invention I produce a stamped fibrous wall and ceiling covering which can retain its embossed decorations permanently, owing this property not to any finish or dressing material but only to the nature of the stuff or material employed in its manufacture. This material consists of a compressed sheet of wadding stamped with relief designs, the front face of the sheet of wadding being decorated in any manner that does not deprive it of the characteristics of a textile material, as for instance by dyeing, by printing colored designs or fine fiutings, or the like.

Owing to the great compressibility of the wadding it is possible to obtain on a sheet of wadding, Without great expenditure of power, embossings which are more raised than those of the ordinary 'wall coverings which are obtained by displacement of a mass carried by a substratum of cloth or paper or by stamping paper or still wet papier-mach. Moreover, when the wadding is once embossed it assumes a degree of permanence which dispenses with the necessity for fixing the reliefs by a dressing material, so that, as compared with embossed wall coverings of pile cloth or napped cloth there is attained the advantage both of permanent retention of the textile characteristics of the front surface and of a cheaper manufacture; the latter arises both from the fact that wadding is cheaper than a cloth capable of yielding reliefs of the same height and from the fact that there is no need to use any dressing material for the fixing of the reliefs.

The wadding sheet to be stamped can be Specification of Letters Patent.

formed advantageously by several superposed wadding webs of which at least one is impregnated with .a water-proofing or hardening substance such as casein, glue or varnish and of which at least that which forms the front surface of the wall or ceiling cov ering, is dyed in the mass.

For the manufacture of the new stamped fibrous wall and ceiling covering I may, for instance, proceed as follows: Several dried thin webs of wadding made from wood cellulose are rolled up together to form a thick wadding sheet, the front face of this sheet being formed at least by one of the said webs of wadding manufactured from dyed wood cellulose, while at least one of the other webs has been impregnated with a solution of casein, glue or varnish.

In the drawing Figure 1 is a sectional view of such a thick wadding sheet made of several webs and Figs. 2 and 3 are respectively a front view and a sectional view of the same wadding after it has been compressed and embossed.

The wadding sheet of Fig. 1 is formed of 9 superposed webs 1, 2, 3, 4, 5, 6, 7, 8, 9, of which the webs 1 and 2 forming the front face are dyed in the mass, while the webs 8 and 9 forming the back face of the wadding sheet havebeen impregnated with a solution of casein, glue or varnish. On this thick sheet of wadding are then first printed, if desired, colored designs or fine or shallow flutings by means of engraved, and if necessary, heated cylinders; or other decorations or ornaments known in the wallcovering industry may be applied; the dried wadding sheet is now subjected once or oftener to the pressure of engraved, and, if necessary, heated cylinders or plates, so as to compress the wadding and to stamp it with the designs in high relief, which give to the sheet the character of a plastic wall or ceiling covering, without depriving it of the characteristics of a textile material.

In Figs. 2 and 3 a are the high embossings and b the fine fiutings between the said embossings, formed on the front face of the wadding by the said stamping.

Instead of impregnating, as specified, at least one of the wadding webs, which do not form the front face of the sheet of wadding, the wadding sheet may be treated without previous impregnation and may be coated on the back, before or after embossing, with a water-proofing or hardening agent,

such as a solution of gelatin containing alum or a varnish. A paper or textile web can also be pasted on the back of the sheet of wadding before or after the sheet has been compressed and embossed.

If the wadding sheet forming the wall and ceiling covering is made of several wadding webs united together of which that forming the front face of the covering is constituted by a very thin fleece dyed in the mass, the relief parts of the covering appear darker than the ground. v

I am aware of the fact that embossed imitation leather and paper have already been manufactured by impregnating throughout one or more fleeces or sheets of textile fibers with rubber, gelatin, resin, or tannin substances, cementing the fibers together, but depriving the material of its textile character, that is to say of the appearance of a textile fabric and reducing its compressibility in such a manner that after drying of the material high reliefs cannot be embossed in it. From these leather or paper imitations the wall and ceiling coverings of the present invention differ in that the said coverings offer high reliefs on a surface having retained its textile characteristics or appearance.

Applicant is aware of the fact that leather and paper imitations have already been manufactured by impregnating throughout one or more fleeces or webs of textile fibers with a solution of rubber or of analogous substances, cementing the fibers together, depriving the material of its textile character that is to say of the appearance of a textile fabric and reducing its compressibility in such a manner that after drying of the material high reliefs cannot be embossed in the same. From these leather or paper imitations the wall or ceiling coverings of the present application differ in that these latter ofler high reliefs on a surface having retained its textile characteristics or appearance.

WVhat I claim is:

1. A stamped fibrous wall and ceiling covering having the characteristics of a textile material, formed by a sheet of wadding compressed and embossed and having its front face further decorated with fine flutings, substantially as described.

2. A stamped fibrous wall and ceiling covering having the characteristics of a textile material, formed by a sheet of wadding compressed and embossed and comprising at least one layer of fibers, which does not form its front face, impregnated with a waterproofing substance, as described.

3. A stamped fibrous wall and ceiling covering having the characteristics of a textile material, formed by a sheet of wadding compressed and embossed and comprising at least one layer of fibers, which does not form its front face, impregnated with ahardening substance, as described.

4. A stamped fibrous wall and ceiling covering having the characteristics of atextile material, formed by a sheet of wadding compressed and embossed and comprising at least one layer of fibers, which does not form its front face, impregnated with a hardening substance, the said sheet of wadding being further decorated on its front face with fine flutings, substantially as described.

5. A stamped fibrous wall and ceiling covering having the characteristics of a textile material, formed by a sheet of wadding compressed and embossed and comprising at least one layer of fibers, which does not form its front face, impregnated with a waterproofing substance, the said sheet of wadding being further decorated on its front face with fine flutings.

In witness whereof I have hereunto signed my name this 4th day of October 1913, in the presence of two subscribing witnesses.
